"Pendahuluan: Cedera iskemia reperfusi CI/R merupakan masalah serius yang dihadapi pascahipoksia menyebabkan kerusakan sel yang letaknya berjauhan remote organ injury. Strategi yang digunakan untuk mengurangi kerusakan hepar pascaiskemia adalah melalui penerapan ischemic pre conditioning PI/R dan hiportemia. PI/R telah terbukti mengurangi kerusakan jaringan melalui mekanisme resistensi terhadap iskemia dan kebutuhan energi lebih rendah. Sedangkan hipotermia menghambat laju kematian sel sehingga dapat diterapkan sebagai terapi awal pada tatalaksana trauma dengan tujuan mencegah kerusakan bertambah berat. Penelitian ini bertujuan untuk diketahuinya efek protektif PI/R dan hipotermia terhadap perubahan morfologi jaringan hepar dan peningkatan kadar malondialdehyde MDA sebagai respon stress oksidatif. Metode: Studi eksperimental pada 24 ekor Oryctolagus cuniculus. Kelompok iskemia dilakukan ligasi arteri femoralis komunis dalam pembiusan selama empat jam untuk menginduksi iskemia, kemudian ligasi dibuka dan kelinci dibiarkan beraktivitas selama delapan jam. Pada kelompok PI/R dilakukan ligasi berulang arteri femoralis komunis kanan selama dua menit, dilepaskan tiga menit sebanyak dua siklus, kemudian diligasi selama empat jam. Kelompok hipotermia, dilakukan iskemia disertai membungkus ekstremitas bawah kanan dengan es, suhu antara 31-33oC Kemudian dilakukan laparotomi, dan diambil organ hepar. Pemeriksaan histopatologi hepar dilihat dari 3 zona, sentral, midzonal, perifer. Untuk menilai stress oksidatif jaringan dilakukan pemeriksaan biokimia dengan malondialdehyde MDA. Dilakukan uji statistik terhadap variabel tersebut dengan kemaknaan. Hasil: Pada pemeriksaan histomorfologi terdapat perbedaan perubahan histomorfologi pada sampel kontrol PI/R, dan Hipotermia terhadap iskemia (p<0,05). Derajat kerusakan histomorfologi pada kelompok PI/R lebih rendah dibandingkan kelompok iskemia reperfusi pada semua zona (p sentral = 0,015, p medial = 0,019, p perifer = 0,026). Analisis kadar MDA memperlihatkan terjadi peningkatan pada kelompok iskemia reperfusi menujukkan adanya stress oksidatif. Kadar MDA pada kelompok PI/R dan hipotermia lebih rendah dibandingkan kelompok iskemia.(p = 0,002). Konklusi: Keadaan iskemia reperfusi menyebabkan perubahan histomorfologi dan stres oksidatif sel–sel hepar. PI/R dan hipotermia mempunyai efek protektif pada cedera iskemia reperfusi.

Introduction: Ischemia-reperfusion injury IRI is a serious problem occuring after hypoxia it causes injuries to cells located remotely from one another remote organ injury. Strategies used to decrease hepatic injuries post ischemic condition are composed as ischemic pre-conditioning IPC and hypothermia management procedures. IPC has been proven to decrease tissue injuries through resistance mechanisms towards ischemia and lower energy requirements. Meanwhile, hypothermia detained the rate of cell deaths, therefore, it can be used as initial therapy on trauma management in order to prevent worsening of the injuries. This research aims to evaluate the protective effects of IPC and hypothermia towards morphological changes of hepatic tissues and the increase of malondialdehyde MDA level as a response to oxidative stress.Methods.

Methods: This research is an experimental, descriptive-analytical study on 24 Oryctolagus cuniculus. The specimens were divided into four groups, with one group as control. The ischemia group underwent femoral artery ligations under anesthesia for four hours to induce ischemia. Afterwards, the ligations were released and the rabbits were free to roam for eight hours. The IPC group underwent repeated ligations of right communal femoral artery for two minutes and three minutes of release in two cycles. Afterwards, the arteries were ligated for four hours. The hypothermia group underwent ischemia and wrapping of right lower extremities using ice, with temperature around 31-33oC. Afterwards, laparotomies were conducted on all groups to obtain and evaluate the liver. Hepatic histopathology assessment were conducted from 3 zones, the central, midzone, and peripheral zone. To evaluate the effects of oxidative stress on the tissue, a biochemical assessment with malondialdehyde MDA was conducted. Statistical tests were then conducted to assess the relationship between the variables with significance level p < 0.05.

Results: On histomorphological assessment, there were histomorphologic changes on control samples for IPC and hypothermia compared to ischemia p < 0.05. On MDA level analysis, there were increases in all four groups p < 0.05. However, there were no significant differences for the histomorphological changes when compared between central, medial, and peripheral zones.

Conclusion: Ischemic reperfusion condition causes histomorphological changes and oxidative stress on hepatic cells. IPC and hypothermia have protective effects from ischemia-reperfusion injuries. The protective effects of IPC was better than hypothermia."

The Effect of Preconditioning and Hypothermia in Ischemia Reperfusion Injury to the Endothelial Cells from Peripheral Blood Vessels in Oryctolagus cuniculusM Febriadi Ismet1 Yefta Moenadjat2 Aria Kekalih31General Surgery Science Study Program, Faculty of Medicine Universitas Indonesia2Department of Surgery, Dr. Cipto Mangunkusumo National General HospitalIntroduction. Ischemia reperfusion injury IRI is a serious problem in the post hypoxia period, which causes remote organ injury. Ischemic preconditioning IPC is a phenomenon where tissues are subjected to repeated hypoxic stimulations to protect against subsequent prolonged period of ischemia. Hypothermia during ischemia reperfusion injury HI decreases metabolism of cells including their response to ischemia. The goal of this study is to investigate the effects of interventions such as IPC and HI on the morphology of endothelial cells in blood vessels and the increased level of malondialdehyde MDA as an oxidative stress response in endothelial tissues of distal common femoral artery and vein obstruction ischemia and its contralateral IRI.

Method: This is a descriptive and analytic experimental study using Oryctolagus cuniculus. In the IRI group, the common femoral artery was ligated during anesthesia for four hours to induce ischemia. In the IPC group, the right common femoral artery was continually ligated for two minutes, which was then released for three minutes for two cycles, and then ligated for four hours. In the hypothermia group, the common femoral artery was ligated for four hours and the right lower extremity was wrapped in ice with the target temperature range between 31 33o C. Then the arteries from the three interventions were unligated and the rabbit was released to observe its activity for eight hours. Next, samples of artery and vein distal from the ligation ipsilateral and its contralateral were obtained for histopathological and biochemical examinations. The biochemical analysis was performed using malondialdehyde MDA.

Results: The histomorphological examination showed significant difference in the injury scores between the endothelial tissues from ipsilateral artery and vein in the three interventional samples compared with control, and the scores for the preventive intervention groups were better than the IRI sample p0.05.

Conclusion: Ischemic reperfusion injury can cause not only endothelial dysfunction in the ischemic area, but also remote organ injury. Endothelial lining injury can be prevented by IPC and HI. The elevated level of MDA is a physiological response of tissue after ischemia reperfusion injury which could be found on IRI, IPC, and HI."

"Pendahuluan: Revaskularisasi segera jaringan yang telah iskemia, tidak selalu membuahkan hasil yang diharapkan. Berbagai reaksi yang timbul dari pembentukan reactive oxygen species dan aktivasi sistem komplemen menyebabkan cedera iskemia reperfusi. Ischemia preconditioning PRC dan hipotermia diduga dapat mengurangi efek dari cedera iskemia reperfusi. Metode: Penelitian eksperimental ini adalah lanjutan dari penelitian sebelumnya, di mana dilakukan uji statistika terhadap kelompok kontrol dan tiga kelompok perlakuan, yaitu cedera reperfusi IRI, ischemia preconditioning PRC, dan hipotermia. Data kelompok kontrol dan IRI diambil dari penelitian sebelumnya. Kelompok PRC dan hipotermia masing-masing menggunakan enam hewan coba Oryctolagus cuniculus. Pada kelompok PRC dilakukan ligasi arteri femoralis komunis kanan selama dua menit, dilepaskan tiga menit sebanyak dua siklus. Pada kelompok hipotermia dilakukan pembungkusan ekstremitas bawah kanan dengan es. Kemudian kedua kelompok dilanjutkan dengan dilakukan pengikatan arteri femoralis komunis kanan selama empat jam, dan kemudian ikatan dilepaskan selama delapan jam. Kemudian dilakukan laparotomi, dan diambil organ gaster. Bagian antrum diambil untuk pemeriksaan histopatologi dan biokimia. Pemeriksaan biokimia dilakukan menggunakan malondialdehid MDA. Hasil: Uji hipotesis dari perbedaan histopatologi dan biokimia secara keseluruhan bermakna secara statistik. Derajat kerusakan secara histopatologi pada kelompok ischemia preconditioning lebih rendah dengan signifikan dibandingkan kelompok IRI; namun secara biokimiawi, lebih tinggi namun tidak signifikan. Derajat kerusakan secara histopatologi pada kelompok hipotermia lebih rendah namun tidak signifikan dibandingkan dengan kelompok IRI; namun secara biokimiawi, lebih tinggi dengan signifikan dibandingkan dengan kelompok IRI. Bila membandingkan PRC dan hipotermia, secara histopatologi, PRC lebih rendah dengan signifikan. Secara biokimia, rerata PRC lebih rendah namun tidak signifikan. Kesimpulan: Ischemia preconditioning memiliki efek protektif terhadap dampak destruktif yang yang dihasilkan oleh ischemia reperfusion injury terhadap organ jauh. terhadap organ jauh. Hipotermi juga memiliki efek protektif, namun tidak sebaik ischemia preconditioning.

Background: Immediate revascularization of ischemic tissue, does not always produce the expected results. Various reactions that arise from the formation of reactive oxygen species and the activation of the complement system cause ischemia reperfusion injury. Ischemia preconditioning PRC and hypothermia are thought to reduce the effects of ischemic reperfusion injury.

Methods: This experimental study was performed on the control group and three treatment groups, namely reperfusion injury IRI, ischemia preconditioning PRC, and hypothermia. Two experimental animals were used in control group and six experimental animals were used in IRI, PRC and hypothermia groups. In IRI group, right common femoral artery was ligated for four hours, and released for eight hours. In the PRC group, ligation of right common femoral artery was performed for two minutes and released for three minutes in two cycles. In the hypothermia group, right lower extremity was wrapped with ice. Subsequently, in the two groups, the right common femoral artery was ligated and released like IRI group. Then, laparotomy was performed and the stomach was taken. The antrum part is acquired for histopathology and biochemistry assay. Biochemical examination was performed using malondialdehyde MDA.

Results: The hypothesis test of histopathologic and biochemical differences in general was statistically significant. The degree of histopathological damage and MDA in IRI group was significantly higher than control group. The degree of histopathological damage in the PRC group was significantly lower than in the IRI group but biochemically, higher but not significant. The degree of histopathologic damage in the hypothermia group was lower, but not significant, compared to the IRI group but biochemically, significantly higher than the IRI group. When comparing PRC and hypothermia, histopathologically, PRC is significantly lower. Biochemically, the mean PRC is lower but not significant.

Conclusion: Ischemia preconditioning has a protective effect on the destructive impact of ischemia reperfusion injury in distant organs. Hypothermia also has a protective effect, but is not as good as ischemia preconditioning."

Introduction: Ischemia occurring in a location in the body results in damage to distant locations; this condition is known as reperfusion injury. Intestinal vilia is a target organ of the occurrence of damage to reperfusion injury and a motor failure of multi-organ systemic. The dreaded hypothermia in shock actually shows an advantage because it protects the occurrence of villous damage. This study aimed to compare the protective effect of hypothermia and pre conditioning on ischemia.

Methods: Experimental studies were conducted on New Zealand White rabbit (n = 18) with one control group (ischemia) and two treatment groups (hypothermia and pre-blocking). Conducted ligation a. iliaca communist for 4 hours, moderate hypothermia (28°C), and preconditioning ischemia in each group. Then the rabbit is left alive for 8 hours. After decapitation, ileum samples were taken for histopathologic examination.

Results: Of the 18 experimental rabbits, 1 had dropped out due to infection. Scores of villus intestinal damage were performed based on modified Pusponegoro criteria with a minimum score of 4 and a maximum of 2. The pre-treatment group experienced the least damage (=6.2) followed by the hypothermia group (=7,1).

Conclusion: Pre conditioning shows the least damage; in other words gives a better protective effect compared to other groups."
